so long gone by that name, that it would be unadvisable 

 to change it. It is probably his V. lata. Dale called 

 it Pectunculus fasciatus ; and this name has the pre- 

 cedence of all others. I will adduce a few out of the 

 numerous synonyms published by different authors : 

 V. edulis, Chemnitz ; V. rhomboides, Pennant ; V. Beu- 

 dantii, Payraudeau; and V. virago, Loven. In its 

 younger state it appears to be the V. nitens of Scacchi, 

 but not of Turton.

Body thick, oblong, greyish, yellowish, or very pale bluish- 

 white, sometimes tinted with pink : mantle having wavy or 

 jagged edges, which project a little beyond the valves ; the 

 indentations or folds are stronger at the sides than in front ; 

 within the margin are a few scattered white tentacular papillae : 

 tubes nearly equal in length and diameter, the upper being a 

 trifle longer than the lower, but not quite so large and more 

 conical and contracted at the opening ; they vary in length 

 from being only one-half to quite as long as the shell is broad ; 

 the upper serves for excretal and the lower for alimentary 

 purposes; both are cylindrical or funnel-shaped, and joined 

 together until about one-fourth of the distance from the orifices, 

 where they diverge, the upper curved backwards and the lower 

 forwards ; they are closely wrinkled across, and the upper or 

 outer third portion is irregularly traversed with brown streaks 

 or lines; the orifice of each tube is tinged with brown of 

 various shades, red, orange, or flake-white, and fringed with 

 short finely ciliated filaments, those of the upper tube being 

 plain, and the other set arranged in a double row ; the inner 

 row consists usually of a few only, which are erect and longer 

 than the outer row, and branched or studded at their sides 

 with short points, like the gills of some jNudibranchs ; the 

 outer row is twice as numerous, very much shorter, and folded 

 outwards; the edge of the lower orifice is considerably ex- 

 panded, like a bell, when the animal is feeding : gills pale
